Unless you are trained to recognize mint errors, you probably won't recognize them. They are scarce and it's highly unlikely you would have a dozen within a group of 100-200. Also, production methods from older eras were poorer so errors command less value. The coins pictured here are corroded and there is nothing you can do to undo the environmental damage. I suggest you put them all together for a photo to see whether any are worth more.

I've over one hundred Straity Settlement coins and one dozen or so seem to exhibit mint errors but I'm not sure. I wish to sell all my SS coins but also not sure if auction is the correct way to go. Do I sent attached coin for grading?
